I’m not sure what their are all about… I mean come on we all know that you have to put them in water and watch them grown… but I want to know how long they live… I looked them up… but all it said was that they would reproduce and all this other stuff… So if they reproduce… do I need to buy a bigger tank… is this going to be a huge project that I should avoid. is it like fish? or what… could someone please help me for experience only. I don’t want any references to a web page. if you’ve had them or have them let me know how it was…. thanks
